PALM PRE wont Start after a failed 1.3.1 update

I tried updating my palm pre using the webos doctor 1.3.1 o2. The update was not succesful, it came with a msg cannot reset the device, and the palm pre itself stuck at the screen with big arrow pointing down at an integrated circuit. Trying to turn off the device without any success, I pulled out the battery, and now it won"t even start. Not even in usb mode. Please help.
